CommunityJun 18, 2017Beach Mirror

Canada’s weather agency has issued a severe thunderstorm warning for northern York Region June 18.

Environment Canada is calling for heavy rainfall in Newmarket, Georgina and elsewhere in northern York, with amounts in excess of 50 millimetres within one hour possible. Damaging winds are also possible.

The warning was issued at 4:21 p.m.

Environment Canada issued a severe thunderstorm watch at 10:35 a.m. for much of southern Ontario, including Toronto, York, Mississauga and Brampton, in advance of numerous thunderstorms that could occur.

The watch remains in effect in areas closer to Lake Ontario not affected by the warning.

The main causes of concern are damaging wind gusts and torrential downpours that can result in rainfall amounts exceeding 50 millimetres.

Large hail could also fall, causing damage to property and possible injury.

Environment Canada advises that strong wind gusts can toss loose objects, damage weak buildings, break branches off trees, and even overturn large vehicles. Heavy downpours can also cause flash floods and water pooling on roads.

Lightning is also a potential threat, the government agency warns.

Severe thunderstorm watches are issued when atmospheric conditions are favourable for the development of thunderstorms that could produce large hail, damaging winds, and/or torrential rainfall.

The Office of the Fire Marshal and Emergency Management recommends people take immediate cover if threatening weather approaches.
